Don't forget, this is the Neo Geo POCKET-- not the "full" Neo Geo system that was a home/arcade unit (that was the $500 one).
Still a great, great system. My NGPC has probably seen much more use since I got it (about 3 years ago now) than my GBA ever has... they did a great job with the system.
I see it appears to be sold out now.
At least at the $29.99 price-- it does say it's Amazon's #1 seller. good to see the system have a last little fling with popularity...
